Goal

How to rebuild the MIR on a T10000 tape cartridge using VOP.

Solution

When a T10000 tape cartridge needs to have the MIR rebuilt, use the "Make MIR" utility in VOP on an offline drive.

Refer to [Document: 1014070.1] on where to acquire VOP application.

Use the "Rebuild MIR" utility in the Virtual Op Panel (VOP) application using the following steps.

1. Connect to a drive using the VOP application ... File -> Connect to Drive
2. Take the drive offline ... Drive Operations -> Set Offline
3. Open the MIR rebuild Utility ... Drive Operations -> Format Tape
4. Run the MIR rebuild Utility ... Select Rebuild MIR and click the Make button
5. Insert the tape to be rebuilt into the drive

This method will:
1. Index all of the block entries in the MIR.
2. Rebuild the defect table entries in the MIR and RFID.
3. Ensure that there is a match between the RFID and MIR table entries.

This utility will run until it reaches the End of Data marker on the tape.  Depending on how much data is on the tape it could take a few minutes or a few hours.

Notes:
 - If the tape was previously involved in a write perm error it probably will not have an EOD block in which case you will see and A737 error when you try to run the rebuild MIR Utility. In this case it is best to have the customer copy the data off of this tape an onto another tape then certify the tape to ensure there is no physical damage to the media. The "Copy To" tape will have a new MIR when the copy operation completes.
